Inscribed Gentian

#5bd7d1
Notes

Inscribed Gentian (#5BD7D1) is a true cyan with a cool character. It leans cool, sitting on the blue, green, and violet side of the wheel. Quiet and dependable, a fit for product UI and data visualization. Its HSL profile (177°, 61%, 60%) places it in the balanced band at a mid lightness. It works across type, buttons, and borders, saturated enough to feel deliberate but balanced enough to not fight the rest of the palette. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Inscribed
adjective

Latin īnscrībere, to write upon — past-participle of inscribe. As a color modifier, inscribed implies a clear-and-text-or-pattern-cut quality, the crisp color of Roman-Imperial-period monumental-stone inscription-and-monumental-text incised-relief. Sits at the crisp-and-incised end of the grid, parallel to etched and engraved in usage.

Gentian
noun

The genus Gentiana — Alpine and high-meadow perennials whose deep saturated blue flowers are among the bluest in the European flora. Gentian-blue names a color category. The color refers to a fresh G. acaulis (stemless gentian) in Alpine meadow: a saturated, slightly cool deep blue with the matte finish of trumpet-shaped flower.

Moderately saturated colors gain a small bump in P3 — the difference is usually visible side-by-side on wide-gamut hardware but won't change the character of the color.
